بررسی صفات کمی و کیفی ارقام و لاینهای گندم نان در آزمایشات مشاهده ای و مقایسه عملکرد بین المللی دیم

In order to evaluation of grain yield and some agronomic characteristics of some spring bread wheat lines and genotypes this experiment was conducted in Moghan Agricultural Research Center in 2004-2005. This experiment included five parts: 15thHRWSN 22thSAWSA WON-D ARWYT-LR/SC RWYT-LR/CA with 597 treatments with two checks (Zagross and Kohdasht). Each plot size in yield trial experiment was planted (1.2m5اm = 7.2 m2) in two replications and observation nurseries were planted (0.6m 1m ) plot size without replication. The result of ANOVA analysis for grain yield in ARWYT-LR/SC experiment showed we have significant differences between treatments, 15 genotypes was selected are including : 2, 4, 7, 8, 11, 13, 14, 15, 20 and 23. In the RWYT-LR/CA experiment there is no significant differences between genotypes, but based on grain yield we had 10 genotypes in the same class of the check is. In the experiment of 15thHRWSN of 79 genotypes of total lines selected. the best genotypes ( number 52, 56 and 296 ) had more than 5 ton per hectare grain yield. These lines are resistant to yellow rust, head scab. In the experiment of 22thSAWSA we selected 54 genotypes of total lines. In the experiment of WON-D we selected 58 genotypes based on grain yield and other best characteristic trial in comparing with check.
